Thank you @ballardw for your response. Actually, I am trying to see if there is any matrix kind of relationship between genotype yield and different environments, the genotype and environment interaction (GEI) effect. I used data set peanut and FixedBiplot macro ( ref book: Genetic Analysis of Complex Traits using SAS) to generate a GEI biplot under the fixed model framework as given in the book but couldn't get the outputs. I have used following SAS codes to invoke a FixedBiplot macro to produce GEI or GGE biplots: goptions cback=white;
options nodate ls=75;
proc import datafile="c:\peanut.xls" out=peanut replace; run;
%include 'c:\FixedBiplot.sas';
%FixedBiplot(peanut,15,10,4,yield,env,gen,rep,geno); When I run this code in SAS University Edition, it shows error at GPLOT procedure as said above, I just thought that if SGPLOT is advanced than GPLOT, then older codes must have been possible to convert in the SGPLOT format, there may some other ways to produce biplots using this macro, I don't know. The peanut data set and macro and expected biplots are attached for your information. Hope for the solution. Thank you.
